Dear all,
OLSRd v1 has been in 'freeze' mode for a long time now, after I sent out
an email looking for a new maintainer on Oct 31st 2018.
At this time I've decided to completely stop maintaining OLSRd v1, and
since nobody applied for the task of being the new maintainer, OLSRd v1
will now go into hard-freeze mode.
You are all advised to switch to OLSRd v2 or to another ad-hoc routing
protocol implementation.
So long and thanks for all the fish!

The problem is, none of them are backwards compatible. Imagine upgrading every node on your network on the same weekend. (It'll eventually have to be done, but wow!)
